Hear, o heavens, and give ear, o earth! For the Lord has spoken.
God, who at various times and in various ways spoke in time past to the fathers by the prophets, has in these last days spoken to us by his Son.
Isaiah 1:2; Hebrews 1:1.2
Within the limits of our existence as creatures we cannot have any conception of God. If any human being wanted to comprehend God in His essential being with his intellect and thinking, he would have to be God. Nevertheless, God has spoken, expressing Himself in a language accessible to humans.
The creation reveals His existence (cf. Psalm 19:1-7). We see the infinite power and wisdom of the Creator in it. He has spoken by means of the angels (cf. Acts 7:35; Galatians 3:19) and the prophets. He has spoken in the Person of His Son. Christ is the revelation of God in the fulness of His being.
Finally, God still speaks through the Bible, the written Word. All that we are able to know about Him and the Lord Jesus Christ is recorded in this book.
The revelation of God has essentially a moral character. It does not address our intelligence as much as our conscience and our heart. To our conscience He presents Himself as a holy, righteous God, the God of truth, whose claims and demands are absolute. The evil in us and that which we have committed He can therefore only condemn. To our heart He reveals Himself as the God of love, who gave His Son. For all who turn to Him He has passed the judgment that we deserved on Christ.
May He be praised eternally for such grace!
